High Quality Content by WIKIPEDIA articles! California Institution for Men (CIM) is a male-only state prison located in the city of Chino, San Bernardino County, California. It is often colloquially referenced as "Chino." In turn, locals call the prison "Chino Men`s" or just "Men`s" to avoid confusion with the city itself. The institution is a reception center for parolees who are returning to custody and a place for newly committed felons from several counties in Southern California.
